Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the utility model it include barrel 1, feeder sleeve 2, the valve body connected with feeder sleeve, positioned at valve
The syringe needle 3 of body bottom and the motor 4 positioned at body top, the valve body include valve bonnet 5, valve body 6 and valve seat 7, described to drive
Dynamic motor is connected with by drive shaft 8 in the screw rod 9 for extending downwardly through that valve bonnet and valve body are stretched into valve seat, the valve body
It is connected with the radial spring baffle plate 10 that can be moved up and down along valve body, the screw rod and is socketed with positioned at valve bonnet and radial spring
Spacing seam portion 12, the valve seat can be carried out to radial direction spring stop by being provided with the top of spring 11 between baffle plate, the valve seat
Side offers radial direction through hole and neck respectively, and the radial direction through hole is connected with feeder sleeve, is fitted with being locked in the neck
The locking elastomer block 14 that handle 13 is press-fitted.
Bonnet is threadedly coupled with valve body, and screw rod, which is located inside the boss for being provided with and radially swelling at the top of valve seat, valve seat, to be opened up
There is corresponding step, driving the tip of the axis offers screw rod mounting groove so that screw rod is fixed.Normality lower spring is compressed in radially
Between spring stop and bonnet, such spring can provide a downward active force, radial spring baffle plate to valve seat
In order to ensure reliable transmission of the motor to screw rod, motor can be connected by shaft coupling 15 and drive shaft
Connect, motor, shaft coupling, drive shaft, screw rod and valve seat are sequentially coaxially installed.Revolved to ensure that screw rod drives in driven shaft
Turn the bearing 16 for being fitted with coordinating with screw rod in smoothness, seam portion；In order to ensure the sealing in rotary course, colloid is prevented
Leakage, can be located at below bearing in the step of valve seat and set sealing ring 18 around screw rod.
Workflow of the present utility model is as follows：When glue dispensing valve is started working, motor drives shaft coupling and driving
Axle is rotated, and drive shaft drives screw rod to rotate, and the colloid in barrel is entered by feeder sleeve inside valve seat, colloid is constrained on spiral shell
In helical flow path between the outer surface of bar and valve base inner wall, moved and flow downward by the rotational band of screw rod, due to continuing for screw rod
Rotate, the colloid in helical flow path is transported on syringe needle, carry out uniform dispensing, when motor stops, screw rod stops
Rotate, the colloid in helical flow path no longer flows downward, syringe needle stops plastic emitting.
When needing inside cleaning valve seat, rotation lock handle makes locking elastomer block outwards depart from neck, due under normality
Spring gives radial spring baffle plate one downward power, and the downward compression axis of radial spring baffle plate is held, and the power can promote valve seat to have downwards
Mobile trend, but valve seat locking is not allowed it to move down by locking elastomer block under normal conditions, therefore when locking elastomer block is taken out
Rear valve base will automatically disengage valve body, and screw rod can be removed by rotating screw rod, and then valve seat and screw rod radially can be cleaned, and may be used also
Cleaned so that the bearing in valve seat and sealing ring are taken out.Cleaning resets bearing and sealing ring after finishing, then by screw rod pair
In place, the top of screw rod is inserted through bonnet in the mounting groove of drive shaft, and backwards rotation lock handle makes locking for quasi- valve seat insertion
Elastomer block is pressed inwardly into neck, completes assembling.
Preference of the present utility model is to be connected between the radial direction through hole and feeder sleeve by being fed adapter assembly 19, is
Its connection sealing is improved, between the feed adapter assembly and radial direction through hole spring washer 20 is fitted with.In order that valve body,
Motor protecting cover 21, motor protecting cover are arranged with outside barrel and feeder sleeve one organic whole steady operation of formation, motor
By being fed fixed mount 22 and the clamp connection of locking knob 23 between barrel, the valve body side is connected with valve body support 24,
The motor is fixed in valve body cradle top by motor fixing plate 25, and the feeder sleeve is by being fed support 26 and valve body
Support is affixed.
Motor can realize that high accuracy tells glue preferably with servomotor, it is ensured that tell glue uniformity, accord with COB
The manufacturing technique requirent of glue dispensing and packaging.
